NOTE: This is a DRAFT working paper.

Much like the seven layers of the ISO OSI model, the OSP - Open Systems
Phreaking - model is a four-layer abstraction of the levels of access that a
phreak can encounter.  The layers are as follows:

4. Switching - switch control/exploration, loop/test lines

3. Private - voice mail or PBX access

2. Operator - diversion/exploration with access codes, live operators

1. Transmission - beige boxing, line splicing, line piercing

An obvious acronym emerges from the model: SPOT.  A convenient mnemonic
could be "Same Phreak, Other Trunk."

How can this model be useful?  Being a working draft, the complete
usefulness of the OSP model has yet to be explored.  Here are two
possibilities.

- Can be used as a code
	Ex. "I've got a Layer 3 number for you."

- Can describe levels of access as one delves into different numbers/systems
	Ex. Using a Layer 2 number for anonymous Layer 3 access

As can be plainly seen, access becomes increasingly rare, and risky, as one
ascends the OSP model.  Take care with Layer 4, and please feel free to
